I have seen several, at least 4 , threads on other forums of people having problems with One Shot, seems it is not unheard of.
I have not used it, but have just tried the Hornady Unique case lube, reqiures a very tiny amount, just brush a finger on it,fondle the case slightly and size, a brush is good for 4 or 5 cases.
I just tried it with some once fired surp. brass, some cases took as many as 6 tries to full length size, never had one stick out of 100 cases.
I also tried it to quick lube cast bullets before running them in a sizer to seat the gas checks, worked fine.
At the rate the 4oz tub is going down, one should do several thousand cases.
:grin:
